I was on Carnival on Dec 18 and was able to smoke. Following week they banned it in casinos. Glad I wasn't on that week. I understand non smokers arguments about us smokers but when they seat you in the dining room with 6 strangers and the whole dining room is maskless what is the difference. My thoughts are keep sipping your drink when your gambling. Let's see if they will ban drinking next so you have to keep the mask on.
